Abstract
Crack propagates in Al2O3 when Al2O3 is bonded to SUS304 by Ag-Cu-Ti brazing. This crack is due to residual stress in Al2O3. Bonding Al2O3 to SUS304 by pulse current heated bonding after brazing Ag, Cu thin plate to Al2O3, SUS304 was studied for the purpose of prevention of this crack. Effect of residual stress relief was evaluated with thermo-elasto-plastic analysis by FEM and joint properties were investigated by bonding test. Main results obtained are as follows :<BR>(1) It was confirmed with FEM that residual stress in Al2O3 could be reduced by proposed bonding method. Insert of soft metal (Ag, Cu) and thermal load reduction by pulse current heated bonding are effective for residual stress relief in Al2O3.<BR>(2) Crack in Al2O3 doesn't generate and excellent joint strength is obtained by proposed bonding method. Joint strength obtained by optimum bonding parameters is 119-122 MPa (average value) at 4 point bending test.
